Transaction card utilizing voice-activated commands

Abstract:

A transaction card receives sound waves that represent a user command, where the user command identifies one or more transaction restrictions of the transaction card. The transaction card converts the sound waves to a digital signal and identifies, based on an analysis of the digital signal, user command data that identifies the user command. The transaction card sets, based on identifying the user command data, one or more transaction restriction values for the one or more transaction restrictions. The transaction card receives transaction metadata associated with a transaction and determines whether the transaction is compliant with the one or more transaction restrictions. The transaction card causes, based on determining whether the transaction is compliant with the one or more transaction restrictions, the transaction to be processed by a server device, or to be declined.
